SNOW-PLOW.

SPECIFICATION forming part of Letters Patent No. 790,295, dated May 23, 1905. Application filedSeptember 28, 1904. Serial No. 226,264.

To all whom it may concern:

Be it known that I, ELIsHA J. GRANT, a citizen of the United States, residing in Mansfield, in the county of Bristol and State of Massachusetts, have invented an Improvement in Snow-Flows, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts This invention relates to a snow-plow for use on railways, and has for its object to provide a simple and efficient apparatus for the purpose specified and one which can be operated from within the house or body of the plow.

The particular features of this invention will be point-ed out in the claims at the end of this specification.

Figure 1 is a side elevation of one form of snow-plow embodying this invention; Fig. 2, an end elevation of the plow shown in Fig. 1 looking toward the right; Fig. 8, a cross-section on the line 3 3, Fig. 1; and Fig. 4, asectional detail, on an enlarged scale, to be referred to, the section being taken on the line 4 4, Fig. 1.

The snow-plow herein shown as embodying this invention comprises a body portion or platform a, mounted upon trucks 6 of any suitable or usual construction, which are provided with wheels 0. The body portion a is provided, as shown, with, a house or cab 0?, having a "suitable door 0. The body portion a of the snow-plow is provided with an inclined upper surface f at one or both ends, according to whether the snow-plow is to be run in one or both directions. In the present instance the body portion a is shown as provided at both ends with a plow proper; but inasmuch as both plows and their operating mechanisms are of like construction a description of one will sufiice.

In accordance with this present invention the cab or house d is provided with a wedgeshaped projection g, with the sides of which cooperate sliding wings or sections it 2', which are operated from within the cab or house. For this purpose each of the wings or sliding sections it c' is provided on its inner surface with a rack-bar j, which is engaged by a gear on a shaft Z, having bearings in a cross-bar 112. within the cab or house and provided in the present instance with a crank or handle at, by which the shaft may be turned to effect movement of the sliding wings or sections. The sides of the wedge-shaped structure 9 may be provided with openings 0 to afford access to the gear from within the house when desired. The sliding wings or sections it are adapted to be moved diagonally across the inclined front surface f and may be guided by suitable ways or tracks p in the said surface and suitable ways or tracks 9 indiagonally-arranged cross-bars? 8, attached at their rear ends to the wedge-shaped projection g and at their front ends to inclined uprights or bars 9 10, secured to the front end of the inclined surface f. The inclined uprights or bars 9 10 are connected at their upper ends by a cross-bar 12 and are provided with beveled faces 13, (see Fig. 2.) which form cutting edges on the front of said uprights.

Theinclined surface f has pivotally attached to its front edge a movable cutter 14, which extends transversely of said inclined surface to form a front extension thereof, which is capable of being raised and lowered with relation to the rails of the track, so that when in operation the cutter 14 may be close to the rails, as shown at the left in Fig 1, and when not in use it may be-elevated, as shown at the right in Fig. 1. The cutter 14: may be raised and lowered from within the cab or house 0Z, and for this purpose the said cutter is connected near its center by links 16 17 to one end of a lever 18, pivoted to an upright support 20, erected upon the cross-bars 7 8 at their intersection, the said lever extending back into the house or cab through a suitable opening in the top of the wedge-shaped front 9 of said house or cab. Thelink 16 may be provided with a beveled front edge to form a centrally-arranged vertical cutter, as represented in Fig. 2. I r

In operation with the snow-plow herein shown the sliding wings he may be moved into what may be termed their central position (represented in Figs. 1, 2, and 3) when it is desired to throw the snow to both sides ofthetrack, the snow in this case being cut horizontally by the movable front cutter 14 and by the vertical cutter-bars 9 1O 16, and the snow thus cut is forced up the inclined surface f until it meets the wedge formed by the wings it 2' in their central position, which divides the mass of snow forced up the inclined surface f, and the divided mass is deflected by the said wings to opposite sides of the track. When it is desired to throw the snow to one side of the track-as, for instance, the right side-the operator rotates the gear 76, which meshes with the rack-bar j on the wing 2' and moves the said wing into its forward position, and when it is desired to throw the snow to the left of the track the wingt' is moved back beyond the path of movement of the wing it, which is then moved forward by the operator rotating the gear 7:; in mesh with the rackbar on the wing it.

The house or cab (i may and preferably will be provided in its front wall above the wedgeshaped portion 9 with a window or opening 25,through which the operator within the cab may see in front of the snow-plow and observe the working of the same.

I have herein shown the invention as embodied in a snow-plow provided with a cab or house which is practically closed; but I do not desire to limit my invention in this respect, as it is evident the cab may be left open at its top. So, also, only the car body or platform a may be provided with a plow at one or both ends, and in some instances a single sliding wing may be sufficient, according to the location of the road on which the plow is used.

I have herein represented the wings as adapted to be moved by the operator turning the crank or handle; but I do not desire to limit my invention in this respect, as the gears X; may be rotated by power.

1. In a snow-plow, the combination with a body portion provided with an inclined upper surface extended toward the track, and a cab or house having a substantially wedge-shaped front portion, of sliding wings movable diagonally across said inclined upper surface, guideways for said wings, and means within the cab or house for sliding said wings back and forth in said guideways, substantially as described.

2. In a snow-plow, the combination with a body portion provided with an inclined upper surface extended toward the track, of a movable cutter extended transversely of the said. inclined surface and pivotally attached to the front lower portion of the same, a cab or house erected upon said body portion and having a substantially wedge-shaped projection,sliding wings movable diagonally across said inclined upper surface, guides for said wings, gearing to effect sliding movement of said wings, and means to raise the movable cutter, substantially as described.

3. In a snow-plow, in combination, a body portion having an inclined upper surface extended toward the track, a cab or house erected upon said body portion and having a front wall arranged substantially diagonally with relation to said inclined upper surface, a sliding wing provided with a rack-bar, a gear in mesh with said rack-bar, and means to rotate said gear, substantially as described.

4. In a snow-plow, in combination, a body portion provided with an inclined upper surface extended toward the track, a movable cutter extended transversely of the said inclined surface and pivotally attached to the front lower portion of the same, and means to raise said cutter, substantially as described.

5. In'a snow-plow, in combination, a body portion provided with an inclined upper surface extended toward the track, a wing cooperating with said inclined surface and reciprocating thereon, guides for said wing in its bodily movement and means to effect reciprocation of said wing, substantially as described.

6. In a snow-plow, in combination, a body portion having an inclined upper surface extended toward the track, a substantially wed geshaped structure erected upon said body portion, sliding wings arranged on opposite sides of said structure, rack-bars attached to said wings, gears in mesh with said rack-bars. and shafts upon which said gears are mounted, said shafts extending within the said wedge-shaped structure, substantially as described.

7. In a snow-plow, in combination, a body portion having an inclined upper surface extended toward the track, sliding wings mounted to move diagonally across said inclined surface, guides for said wings, and means to reciprocate said wings, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
